CAPE CANAVERAL, Fla. - Launch of a SpaceX rocket with a US weather satellite bound for deep space was called off minutes before liftoff on Sunday due to a technical problem, officials said. Launch had been targeted for 6:10 p.m. EST from Cape Canaveral Air Force Station in Florida. But about 2.5 minutes before liftoff, a problem cropped up with an Air Force radar system needed to track the rocket in flight.
The next opportunity to launch is 6:07 p.m. EST on Monday, said NASA launch commentator Michael Curie.
The rocket carries the Deep Space Climate Observatory, nicknamed DSCOVR, a partnership of NASA and the National Oceanic and Atmospheric Administration.
DSCOVR is expected to replace a 17-year-old satellite monitoring for potentially dangerous solar storms. Tsunamis of charged particles from the sun, called coronal mass ejections, can disrupt GPS and other satellite signals, block radio communications and impact electric power grids on Earth, NOAA said.
